Title: Improvements in and relating to the manufacture of shaped structures made from thermoplastic synthetic materials
IPC: B29C59/12
Filed: 1965-06-11
Abstract: A surface of a shaped structure made from thermoplastic synthetic material is exposed to an electrical discharge in an atmosphere containing a halogen gas in the presence of a polymerizable monomer, thereby producing a sealable surface. The structure may be a film, sheet, pipe, tubing or fabric of e.g. a polyolefin such as polypropylene or polyethylene, polybutadiene, polyvinyl chloride, or polyethylene terephthalate and the monomer may be vinyl acetate, vinyl chloride, acrylic acid or an ester thereof, alpha-methyl styrene, styrene, acrylonitrile, 2-chloroacrylonitrile, a vinyl ether, vinylidene chloride, maleic anhydride, diallyl itaconate or hexachlorobutadiene, or a mixture of such monomers.  The halogens specified are Cl2 and Br2, alone or mixed with each other or with an inert gas, e.g. air or N2.  Gaseous monomers are introduced with the halogen supply.  Non-gaseous monomers may be supplied by dissolving them in e.g. trichloroethylene and blowing N2 through the solution and thence into the reactone zone.  Alternatively, the non-gaseous monomer is applied by spraying or dipping.  In examples, a polypropylene film is treated with Cl2 and hexachlorobutadiene and a polyethylene film is treated with Cl2 and styrene, the carrier gas used being N2.

Title: Improvements in or relating to gas heated liquid heaters
IPC: F23N1/08
Filed: 1936-09-12
Abstract: 481,528. Valve accessories. ASKANIAWERKE AKT.-GES. VORM. CENTRALWERKSTATT DESSAU UND C. BAMBERG-FRIEDENAU. Sept. 12, 1936, No. 24943. Convention date, Sept. 12, 1935. [Class 135] A slow-ignition device for gas heated liquid heaters in which a valve 5 in the gas conduit is maintained open only whilst liquid flows to the heater has a member 10 or 11 for throttling the gas conduit attached to a piston 13 fitting loosely in a dashpot cylinder 14 in the gas conduit. Throttle disc 10, Fig. 2, which may be tapered, is attached by a rod 12 to the piston 13, and substantially blocks a cylindrical gas passage 16 at the base of which seats a spring-loaded gas valve 5 connected by a rod 6 to a diaphragm or like member operated by the water pressure. When the valve 5 is closed, the disc 10 rests on it. Due to the dashpot, the disc 10 descends clear of the passage 16 only slowly after the valve 5 is open. Fig. 5 shows a form where the throttle member 11 is integral with the valve 5 which in this case is loosely guided on the head of the rod 6. The valve spring 9, Fig. 2, will normally close the valve 5 sufficiently rapidly against the pressure in the dashpot cylinder but such pressure may be released on upward movement of the throttle member by a non-return valve in the cylinder or, as shown in Fig. 5, on the piston. In'this case, a spring 19 normally presses the piston 13 against a non-return valve 17 on the rod 12.

Title: Stabilised attitude reference system
IPC: G05D1/04
Filed: 1960-07-19
Abstract: 935,976. Gyroscopic apparatus. LEAR Inc. July 19, 1960 [Aug. 10, 1959], No. 25108/60. Class 97 (3). In an attitude reference mounted on a vehicle for determining an orthogonal set of coordinates by means of angle measuring devices associated with an outer roll gimbal, an inner roll axis supporting gimbal, and an azimuth gimbal, a signal dependent on the sum of the product of the azimuth angle and the sine of the elevation angle and the product of the inner roll angle and the cosine of the elevation angle controls torquing means for the outer roll gimbal. In Fig. 1 a directional gyro 50 and a gyrovertical 12 are mounted in an aircraft or rocket on an outer gimbal 18 the axis of which is parallel to the fore-and-aft axis of the craft. The axis of gyro vertical 12 is erected by precession, a pendulous switch 32 controlling a torque motor 20 acting on gimbal 14, and a pendulous switch 34 controlling a torque motor 36 acting on gyro 12. A gimbal 40 of the directional gyro 50 is maintained in a fixed position relative to the vertical by a torque motor 42 controlled through an amplifier 41 by signal.sresulting from any variation in the relative position of pick-offs 22, 28 associated with gimbals 14, 40. The axis of directional gyro 50 is maintained in a fixed attitude relative to the horizontal by the precessional effect of a torque motor 46 controlled through an amplifier 54 by signals from a pick-off 52. For angles of pitch of the craft below a predetermined high value gyro 12 is maintained in the plane of gimbal 14 by a torque motor 26 acting on gimbal 18 and controlled through an amplifier 30 by signals from a pick-off 28. Pick-offs 48, 56, 22 produce signals representative of heading, bank, and pitch of the craft. Fig. 6 shows the normal connection of pick-off 28 through an amplifier 100 to torque motor 26. Signals from pick-off 22, representing pitch of the craft, control a follow-up servomotor 86 which closes a segment switch 88 during large angles of climb or dive to energize a relay 98 and thereby connect torque motor 26 to the output of a sinecosine resolver 74 adjusted by servomotor 86. The inputs to resolver 74 are from pick-offs 28 and 48, the latter being introduced because it becomes responsive to the position of gimbal 18 when the angle of pitch is large. The signal from pick-off 48 is zero on introduction by virtue of a follow-up servomotor 66 which is, however, locked in position thereafter by a brake 70 energized by operation of relay 98. A sense of control signal appropriate -to climb or dive, respectively, is selected by a reversing relay 92 controlled by a further segment switch 90 operated by servomotor 86. Unduly large signals from pick-off 28 cause operation of a relay 120 which restores normal control. The high angle type of control may be introduced at will by operating a switch 122.

Title: Improvements in or relating to carding machines
IPC: D01G15/82
Filed: 1961-07-13
Abstract: 931,907. Cleaning carding-engines. F. REITERER, L. WINDISCH, and J. NIFENECKER. July 13, 1961 [July 27, 1960], No. 25426/61. Classes 120 (1) and 120 (3). A pneumatic dust removing and collecting system in a carding-engine comprises a housing enclosing a lower part of one or more of fibrecarrying components of the machine. Air is discharged towards one or more locations at which dust is liable to occur or settle, e.g. by the action of mate knives, and through the housing adjacent the enclosed part, and discharged air (with entrained dust and waste fibre) is withdrawn from the opposite side of such location(s) and component. The withdrawn air is filtered and recirculated in the system and waste fibre may be separated from dust and reprocessed. In the cotton card shown in Fig. 1 a filter box 6 is divided by a filter screen 7 into an intake compartment 7a and a blower compartment 7b housing a fan 9 which blows air through a duct 10 into the enclosure formed by the housing 10a, and a deflector vane 12 of a nozzle 11 adjustably directs the air flow across a smooth horizontal or downwardly inclined plate 13 (and, if required, partly against the swift 3). The air is drawn through a secondary filter box 14, comprising coarse and fine filters 15 and 16 which separately remove waste fibre and dust, and returns through suction ducts 20, 21, to compartment 7a. A part of the air from nozzle 11 escapes from the enclosure and carries waste fibre, derived particularly from the taker-in 2, into an evacuation box 17. The waste, augmented by fibres pneumatically swept from filter 15 by periodically closing a valve 22 and opening an air supply valve 23 to direct the main air flow into the box 17, is salvaged by a hinged filter door 18. A suction nozzle 25 draws into the main air stream the dust generated in the vicinity of calender rolls 5a. Access to filter 7 is provided by loaded door 24. Modifications, shown in Fig. 3, include a perforated plate 28a forming with the swift 3 a partial enclosure into which air is directed by an adjustable valve 27 of an inlet 28; a blowing nozzle 29 located within the card flat chain 4, supplied with air by an adjustable valve 26 and co-operating with a suction nozzle 30 leading through duct 31 to compartment 7a; a suction device in the form of a perforated hood 32, over the taker-in 2, connected through duct 33 with compartment 7a.
